Felt vs Rubber Soled Boots – Research by CU Students

CU graduate class of Environmental Engineering have conducted a field research and lab analysis on the cell count of live invasive Didymo cells over time for both felt and rubber soled boots.  Didymo, also called rock snot, is an invasive species in our rivers that may harm the larger aquatic insects within an effected area (caddis, stoneflies, mayflies).  The largest transporter of this disease is thought to be fisherman.  The graph below demonstrates a larger likely hood to carry the disease underfoot while walking around a river with felt vs rubber soled boots.  Live Didymo Cells Felt vs Rubber
